Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application takes priority from Provisional
Patent App. No. 61/833,469, filed Jun. 11, 2013, which is
incorporated herein by reference.
FIELD OF THE INVENTION
[0002] The present invention generally relates to a blood alcohol
monitoring system, and more particularly, relates to a
non-invasive, wearable apparatus and method for continuous and
discreet monitoring and prediction of blood alcohol levels.
BACKGROUND
[0003] Individuals desiring to consume alcoholic beverages
recreationally may need to monitor their alcohol intake as they are
consuming the beverages to avoid serious problems. For example,
someone who wishes to drive after consuming alcohol may need to
ensure that they do not exceed the maximum legal limit. Someone may
wish to consume enough alcoholic beverages to enjoy a pleasant
state of inebriation while avoiding a blackout state. Someone may
wish to moderate their alcohol intake to avoid alcoholism. Since it
is often difficult to determine one's exact degree of inebriation,
especially while inebriated, many people find it difficult to
titrate their alcohol consumption accordingly.
[0004] The most commonly used devices for measuring inebriation are
breath-testing analyzers. Such devices are available for consumers
as well as for law enforcement use. However, breathalyzers have
several serious problems. First of all, they are not discreet--a
consumer wishing to measure their blood alcohol content must blow
into a highly conspicuous device. This may make some users
self-conscious to the point that they would be unwilling to use
such a device, especially when inebriated at a social gathering.
The use of a breathalyzer may carry a further stigma considering
the use of such devices for law enforcement purposes. Secondly, the
more inebriated a user is, the less likely they are to remember to
use a breathalyzer to measure their degree of inebriation. Thirdly,
since traces of alcohol remain in the mouth after drinking, a
breathalyzer is likely to be inaccurate and to overestimate a
user's alcohol content. Finally, since the user's blood alcohol
content is measured only at a few discrete times, it is difficult
to make any sort of prediction of future intake or to help the user
titrate their intake.
[0005] Transdermal alcohol sensors measure the amount of alcohol
excreted by the user's skin. As a person ingests alcohol, most of
the alcohol is metabolized by the liver, but some of it is excreted
with perspiration by the skin; the average person emits
approximately one liter of skin perspiration a day. The amount of
alcohol in the perspiration is correlated to blood alcohol content.
A transdermal alcohol sensor is typically a device that generates
electricity in the presence of ethanol; putting such a device on
the skin allows an estimate to be made of the amount of ethanol
excreted by the skin. The advantage of a transdermal alcohol sensor
is that measurements can be made continuously and are not dependent
on the user's remembering to use the device; furthermore, a
transdermal alcohol sensor is more discreet and easy to hide under
one's clothing.
[0006] Transdermal alcohol sensors are used in law enforcement when
an individual's alcohol intake needs to be monitored by the
authorities. However, they are typically not available for the
consumer market, and law enforcement devices using transdermal
alcohol sensors typically do not offer features that enable a
consumer to easily interact with the device, use it to predict
their blood alcohol content at a point in the future, or use it to
titrate their alcohol intake.
[0007] A need exists for an alcohol sensor device that is discreet
and that allows a consumer to predict their blood alcohol content
at some future point, titrate their alcohol intake, and easily see
their current blood alcohol content.

SUMMARY OF THE INVENTION
[0015] An object of the present invention is to provide a system
and method for continuously measuring a user's blood alcohol
content and displaying the measurement for the user or for another
person or entity.
[0016] Another object of the present invention is to provide a
discreet way to measure and display a user's blood alcohol content
that does not attract undue attention or stigma.
[0017] Another object of the present invention is to provide a
system and method for predicting a user's blood alcohol content at
a future point.
[0018] Another object of the present invention is to provide a
system and method for modeling a user's future blood alcohol
content depending on intended consumption and guiding the user in
their alcohol consumption.
[0019] In its preferred embodiment, the system of the present
invention comprises a wearable alcohol sensor that measures a
user's blood alcohol content, preferably by measuring the amount of
alcohol in the user's insensible perspiration. The wearable alcohol
sensor also comprises a mounting attachment that attaches the
wearable alcohol sensor to the user's body, and a communication
module that communicates with a mobile device such as a smartphone,
a tablet, a computer, or any other similar device. The mobile
device receives data from the wearable alcohol sensor, processes
that data, and presents the results to the user.
[0020] The mobile device preferably comprises an app that
interprets data received from the wearable alcohol sensor. Such an
app can display a user's past blood alcohol history for a given
period of time, display a user's current blood alcohol reading, or
predict a user's future blood alcohol content. The prediction can
be made based on several different assumptions--for example, if the
user consumes no other alcoholic drinks for the rest of the night,
if the user continues drinking at the same rate, if the user
consumes a certain number of drinks of a certain type, and so
on.
[0021] In an embodiment, the mobile device can warn a user when
their blood alcohol content reaches a preset maximum value, and can
cause the mobile device to sound an audible or visible alarm,
vibrate, send an email or a text message, or initiate a phone call.
This would inform the user that their blood alcohol content is too
high without stigmatizing them at a party.
[0022] In an embodiment, the mobile device can also warn other
people when a user's blood alcohol content reaches a preset maximum
value. The warning can be effectuated by a phone call, a text
message, an email, or any other means of communication.
[0023] In an embodiment, the mobile device can take a photo of a
user's surroundings if a user's blood alcohol content reaches a
preset maximum value, and send the photo to other people. This may
be used by a user's friends or family to find the user when a user
is too inebriated to be safely left alone.
[0024] In an embodiment, the system of the present invention can
predict a time at which a user may legally drive a motor vehicle if
a user ingests no further alcohol. This may assist a user in
deciding whether or not to take another drink at a party, or in
deciding when to go home from a party. If a user is too inebriated
to be able to legally drive the same day, the mobile device may
communicate with others, such as a user's friends or family, or a
taxi company.
[0025] In making these predictions, the system of the present
invention may use past blood alcohol content history, a user's
height, weight, gender, and race, or both, to estimate the user's
rate of alcohol metabolism. The system may "learn" the user's rate
of alcohol metabolism over time.
[0026] Since skin-based alcohol sensors have a lag time of about 15
minutes between the time an alcoholic drink is ingested and the
time it is excreted by the skin, the system may have a secondary
sensor to determine when a user is consuming an alcoholic drink.
Such a sensor may use a user's motion pattern (i.e. raising a glass
to their lips), a visual image of a glass in the user's hand, the
scent of alcohol, or any other commonly known phenomena to identify
when a user consumes an alcoholic drink. A user may also be able to
enter manually into the system when he or she consumes an alcoholic
drink.
[0027] The method of the present invention comprises continuously
measuring a user's blood alcohol content by a wearable sensor,
transmitting data from the sensor to a mobile device, and using the
mobile device to analyze the data and to make predictions using the
data.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0028] The present invention now is described more fully
hereinafter with reference to the accompanying drawings, in which
preferred embodiments of the invention are shown. This invention
may, however, be embodied in many different forms and should not be
construed as limited to the embodiments set forth herein; rather,
these embodiments are provided so that this disclosure will be
thorough and complete, and will fully convey the scope of the
invention to those skilled in the art.
[0029] It will be understood that when an element is referred to as
being "on" another element, it can be directly on the other element
or intervening elements may also be present. In contrast, when an
element is referred to as being "directly on" another element,
there are no intervening elements present. It will be understood
that when an element is referred to as being "connected" or

"directly connected" or "directly attached" to another element,
there are no intervening elements present. The terms "upwardly",
"downwardly", "vertical", "horizontal" and the like are used herein
for the purpose of explanation only.
[0030] Unless otherwise defined, all technical and scientific terms
used herein have the same meaning as commonly understood by one of
ordinary skill in the art to which this invention belongs. The
terminology used in the description of the invention herein is for
the purpose of describing particular embodiments only and is not
intended to be limiting of the invention. As used in the
description of the invention and the appended claims, the singular
forms "a", "an" and "the" are intended to include the plural forms
as well, unless the context clearly indicates otherwise. All
publications, patent applications, patents, and other references
mentioned herein are incorporated herein by reference in their
entirety. As used herein, the term "and/or" includes any and all
combinations of one or more of the associated listed items.
[0031] In its preferred embodiment, as shown in FIG. 1, the system
of the present invention comprises a wearable sensor module 100 and
a mobile device 110 (preferably a smartphone) comprising an app
that enables the mobile device 110 to send data to, and to receive
data from, the wearable sensor module 100. The wearable sensor
module 100 preferably comprises an alcohol sensor and a
communication interface. In its preferred form, the wearable sensor
module 100 weighs an ounce or less and has a form factor and color
that is unnoticeable under a user's clothes. The wearable sensor
module 100 may be worn anywhere on the user's body as long as the
alcohol sensor is able to be in direct connection with the user's
skin. For example, it may be worn on the user's upper arm, on the
user's ankle, tucked into a user's bra strap or underwear
waistband, or adhered to any part of the user's body, preferably
hidden under clothing for greater discretion. In various
embodiments, the wearable sensor module 100 may comprise an elastic
strap to enable a user to wear it around their upper arm or ankle,
a clip to attach it to the user's waistband or a bra strap, or
adhesive elements to adhere it directly to the user's skin. Any
other attachment means known in the art of wearable device design
can be used as long as the wearable sensor module 100 is in
continuous and secure contact with the user's skin.
[0032] The wearable sensor module preferably comprises a dermal
seal and spacer 200 that creates a seal between the user's skin and
the alcohol sensor, as shown in FIG. 2. The dermal seal and spacer
200 may comprise a foam pad or pads of a predetermined thickness,
rubber bellows, or other similar elements that maintain the
wearable sensor module at a controlled distance from the user's
skin and create a seal between the user's skin and the alcohol
sensor. It is preferable for the wearable sensor module 100 and the
dermal seal and spacer 200 to be non-allergenic and non-irritating
to the skin.
[0033] As shown in FIG. 3, the wearable sensor module preferably
comprises a housing 340 that contains the alcohol sensor 300, the
communications interface 310, a microprocessor 320, and a battery
330. A dermal seal and spacer 200 are affixed to the housing 340.
The housing 340 is preferably made of plastic or any other material
that is lightweight, non-allergenic, and that does not block
wireless communication; it is preferably skin-colored to make it
more discreet. In an embodiment, the housing 340 can also comprise
one or more control buttons, such as an on/off button, a reset
button, or a manual test button. In an embodiment, pressing the
manual test button will preferably trigger the wearable sensor
module to conduct an alcohol test on the user.
[0034] The wearable sensor module may also comprise trigger
circuitry that triggers the alcohol sensor to test the user's blood
alcohol content--preferably continuously, or at regular or
irregular intervals. Such trigger circuitry may also trigger the
communication module to transmit the test results to the mobile
device. The trigger circuitry may be configurable by the user to
operate in regular interval mode, irregular interval mode, or
continuous mode; the user may also be able to set the intervals at
which testing will be performed.
[0035] The alcohol sensor 300 is preferably any sensor that can
measure a user's blood alcohol level continuously or at
intermittent intervals without the user's active involvement. In
the preferred embodiment, the alcohol sensor is a transdermal
alcohol sensor that measures a user's blood alcohol level by
detecting the amount of alcohol in the user's insensible
perspiration. Such a sensor preferably comprises a fuel-cell module
that generates electricity in the presence of alcohol.
[0036] In alternate embodiments, the alcohol sensor 300 may be an
optical sensor that measures light absorption of the user's skin,
or any other sensor capable of measuring a user's blood alcohol
content continuously or at intermittent intervals.
[0037] The data generated by the alcohol sensor 300 is transmitted
through the communications interface 310 to the mobile device 110,
as shown in FIG. 1. The mobile device 110 is preferably a
smartphone, but can be a tablet, a laptop, an mp3 player, or any
other device that is capable of wireless communication and can be
transported by a user to an occasion involving drinking. The
alcohol sensor 300 preferably takes continuous readings and
continuously communicates with the mobile device 110, but may also
take readings at regular or irregular intervals and communicate
with the mobile device at regular or irregular intervals. The
communications interface is preferably Bluetooth, but may also be
wi-fi, 3G or 4G, or any other wireless communications interface
commonly used in the art. In an embodiment, the wearable sensor
module may transmit its data to the cloud 120 and the mobile device
may retrieve the data from the cloud 120.
[0038] The mobile device 110 preferably comprises a processor, a
memory, and a communication interface, said memory comprising an
app that enables data from the wearable sensor module to be sent to
the mobile device via the communication interface, and enables
commands to be sent to the wearable sensor module from the mobile
device via the communication interface.
[0039] The app preferably performs at least the following
functions. It enables the user to see the data from the blood
alcohol sensor displayed on the screen of their mobile device; it
triggers the wearable sensor module to measure the user's blood
alcohol level; it displays historical data regarding the user's
blood alcohol level; and it predicts the user's future blood
alcohol levels.
[0040] FIGS. 4-7 show several screenshots from the app. A user can
find out their current blood alcohol content by simply activating
the app and going to the measurement screen, which displays the
current blood alcohol reading and a graph of historical blood
alcohol consumption, as shown in FIG. 4. In an embodiment, the app
can also display a warning when the alcohol consumption is
increasing too fast, as shown in FIG. 4. In another embodiment (not
shown), a user can find out their current blood alcohol level by
activating the app on their mobile device and pressing the "Measure
BAC" button. The app then triggers the mobile device to send a
signal to the wearable sensor module, causing the wearable sensor
module to either conduct a reading (if in intermittent mode) or to
send the most current reading of the user's blood alcohol level to
the mobile device (if in continuous mode) and display it. The BAC
reading will then appear on the mobile device screen. Since the
user does not have to perform any action other than pressing a
button on their mobile device screen, and since people check their
mobile devices for many different reasons, it will be possible for
the user to measure their blood alcohol level without being
stigmatized (in contrast, it is very difficult to hide the act of
blowing into a breathalyzer at a party). The BAC reading may be
displayed as a simple number, or it may be displayed in other ways
(such as icons to show how many drinks the user has already had and
how many more drinks the user may have before reaching a
predetermined maximum level of inebriation, or colors to indicate
various levels of inebriation). The user may set a predetermined
maximum allowable level of inebriation ahead of time.
[0041] In an embodiment, the app can also store and display a
user's history of blood alcohol levels as a graph, a data table, or
as any other display. For example, a user may wish to see their
history of alcohol consumption at a party, or over a week's time,
as an inducement to greater moderation. FIG. 4 shows a sample
display of a user's blood alcohol level history, and a warning
given to a user whose alcohol consumption rate is increasing.
[0042] FIG. 5 shows a discreet notification from the app given to a
user whose drinking is increasing. The push notification can appear
over other apps if the user allows it to do so.
[0043] In an embodiment, the app uses the blood alcohol level
history to calculate the rate at which the user metabolizes alcohol
and to learn the user's drinking patterns. This enables the app to
customize its operation to the individual user.
[0044] In an embodiment, the app comprises a prediction module that
enables it to make predictions about the user's inebriation level
depending on the user's individual alcohol metabolism. Since
different people metabolize alcohol at different rates and react to
alcohol differently, the prediction module preferably is able to
learn the user's individual reactions. In an embodiment, the user
can "train" the prediction module by consuming predetermined
amounts of alcohol, entering the amounts into the system, and
measuring their blood alcohol content by means of the wearable
sensor module. The wearable sensor module can then learn how fast
the user's body metabolizes the consumed alcohol and use it to make
more accurate predictions. FIG. 6 shows a sample "training" screen.
In another embodiment, the prediction module uses the user's
height, weight, gender, and other relevant variables to predict the
user's alcohol metabolism. In another embodiment, the prediction
module uses historical data regarding the user's blood alcohol
levels to estimate the level at which the user's body metabolizes
alcohol. The prediction module is preferably able to estimate the
user's future blood alcohol levels in various situations (i.e. if
no more drinks are consumed, if the user keeps drinking at the same
rate, if the user only has one more drink, and so on).
[0045] In an embodiment, the prediction module can warn the user
when their inebriation level is likely to cause problems. For
example, the prediction module can sound an alarm or cause the
mobile device to vibrate when the user is dangerously close to a
maximum predetermined level of inebriation. The alarm can be
discreet to avoid stigmatizing the user. In an embodiment, the
prediction module can trigger a text message to be sent to the user
or a phone call to be made.
[0046] In an embodiment, the prediction module may also alert
others when a user's inebriation level is likely to cause problems.
For example, a woman going out drinking may set her mobile device
to alert her friends when she reaches a dangerous level of
inebriation so that they can help her avoid a dangerous situation.
The mobile device may be triggered to send a standardized text
message, an email, or any other type of message or alert. The
mobile device may also be triggered to take a picture of the user's
surroundings automatically when a maximum predetermined level of
inebriation is reached and to send the picture to others to allow
them to find the user easily.
[0047] In an embodiment, the prediction module can instruct the
user when they need to stop drinking so that they can still drive
home safely. FIG. 7 shows a sample screen from the app, showing the
user's current blood alcohol level and a prediction of how soon it
will be safe to drive. The prediction module may use the user's
current blood alcohol level as measured by the wearable sensor
module and the estimated time of going home to determine what the
user's blood alcohol level is going to be at the time of going
home, assuming the user's typical metabolism rate is known.
Alternately, the prediction module may display an estimated time at
which it would be safe for the user to drive. In an alternate
embodiment, the prediction module may cause the mobile device to
contact the user's friends, family, or a taxi service when the user
reaches a level of inebriation that would make it unsafe for them
to drive home after a party at a reasonable time.
[0048] In an embodiment, the prediction module can model the user's
future blood alcohol content depending on various hypothetical
situations. For example, a user may wish to see if it is safe for
them to consume a particular drink at a given time, followed by
another type of drink at a different time. The prediction module
may comprise a database of typical drinks and their alcohol
content, and may enable the user to select the types of drinks and
the times at which they are consumed and to see what their
individual reaction to those drinks is likely to be. For example,
the prediction module may determine that a user is likely to get
blackout drunk after consuming three drinks of a particular type at
a given time, or that it may be unsafe for a user to drive home at
1 am after consuming two drinks of a particular type at
midnight.
[0049] Since a transdermal alcohol sensor has about a 15-minute lag
time between consumption of alcohol and its excretion by the skin,
the prediction module preferably comprises a way to compensate for
the lag time by estimating the user's blood alcohol content after a
15-minute time interval has elapsed. In an embodiment, the system
comprises another sensor that can determine when a drink is being
ingested; for example, the wearable sensor module can comprise a
second sensor that detects a glass in a user's hand, or detects a
sound, scent, or other phenomenon associated with a user's
consumption of alcohol. The second sensor can then communicate with
the prediction module to alert it that the user is consuming
another drink and to adjust its estimate of the user's current
blood alcohol content. In another embodiment, the user may manually
enter it into the app when they consume a drink. The system can
then use the entered data to adjust its predictions of the user's
blood alcohol content.
[0050] As has been mentioned previously herein, many modifications
and other embodiments of the inventions set forth herein will come
to mind to one skilled in the art to which these inventions pertain
having the benefit of the teachings presented in the foregoing
descriptions and the associated drawings. Therefore, it is to be
understood that the inventions are not to be limited to the
specific embodiments disclosed and that modifications and other
embodiments are intended to be included within the scope of the
appended claims. Although specific terms are employed herein, they
are used in a generic and descriptive sense only and not for
purposes of limitation.
